ZCI Sound

06-07-2007, 03:16 PM

Hi Everyone:

I have a TS3650 and purchased a ZCI. I installed it according to instructions. It seems to work fine, but it makes a noise as the blade side is scraping the side of the ZCI. I did not change blades. The blade appears to be parallel when measured. The trunnion appears tight, but the blade itself will flex when pushed. I am using the stock blade that came with the saw. Could this be the problem?

Mine did the same thing, and I use a razor sharp Ridge Carbide blade. Made an awful racket starting up and especially powering down. There's enough friction / contact to make noise, but not enough to cut the .001 material off. What I did is use a 1 x 3, cut to about 8" long to push on the side of the blade, as I raised it up. This forces the blade to flex slightly and cuts a tiny bit more off the ZCI so your blade gets full clearance. Do this on both sides, taking your blade to full height, and your kerf will be about a hair wider, but the noise will decrease significantly.

Now, this is an incredibly stupid, dangerous task... so be careful. It's wise to have someone else handling the blade adjustment wheel while you push your scrap against the blade. You should NOT push on the blade until the teeth gullet is at least 3/4" above the ZCI so you can push on the flat smooth side of the blade. Do not push hard; it just takes a bit of pressure. Raise the blade relatively fast, so you don't get burns on the side.

I had the same problem when the saw was about 3 weeks old. I had bought a new Freud blade so I put it on. Same thing. I took the blade off and cleaned the bottom end of the spindle (shaft). I don't know what came off but the sound stopped. Must have been some crud holding the blade out of square at the rear of the blade.
